Front Suspension Knuckle - Right for Tesla Model S (2016-2021) | 1030606-00-D

Why This Right Front Knuckle is Vital for Your Model S

• Right-Specific Engineering: Tailored to the Model S’s right front suspension layout, with unique mounting points for the steering tie rod, control arms, and brake caliper. Its design accounts for the vehicle’s asymmetric front-end load distribution, ensuring seamless integration with the 65.3-inch front track width.
• Performance Under Duress: Handles up to 2,200 lbs of dynamic load during aggressive driving—essential for a vehicle that delivers 670 hp (Model S Plaid) and needs unwavering front-end stability.

Core Roles in Front-End Performance

• Steering Responsiveness: Houses the right steering tie rod end, translating every input from your steering wheel into immediate, precise wheel movement. A worn knuckle can create lag or “play” in steering, undermining control.
• Force Distribution: Channels vertical impacts (from potholes) and lateral forces (from right turns) to the upper and lower control arms, protecting expensive bushings and ball joints from premature wear.
• Brake & Hub Stability: Provides a rigid base for the right front brake caliper and wheel hub, ensuring consistent braking performance and vibration-free rotation at speeds up to 155 mph.

Signs Your Right Front Knuckle Needs Replacement

• Pulling to the Left: Vehicle drifts left on straight roads, a clear sign of right knuckle deformation throwing off alignment.
• Steering Wheel Shake: Vibrations at 50+ mph, especially during braking, caused by a warped knuckle disrupting wheel balance.
• Uneven Right Tire Wear: Excessive shoulder wear on the right front tire (vs. left) signals misalignment from a bent or cracked knuckle.
• Clunking in Turns: Metallic “knocks” when steering right, indicating loose mounting points or internal damage.

Built to Tesla’s Uncompromising Standards

• Material: Forged from SAE 4140 chromoly steel (tensile strength 1,100 MPa), heat-treated for superior fatigue resistance—outperforming standard steel in withstanding repeated stress.
• Precision Machining: CNC-machined to ±0.01mm tolerance, ensuring the steering axis and hub bore align perfectly. This eliminates “camber thrust” that causes unintended pulling.
• Corrosion Protection: Multi-layer coating (zinc plating + epoxy primer + topcoat) passes 1,500-hour salt spray testing, ideal for snowy or coastal regions.
• Integrated Features: Pre-drilled holes for ABS sensors and brake line brackets, ensuring compatibility with the Model S’s advanced safety systems.

Professional Installation: Non-Negotiable for Safety

1. Prep Work: Disconnect the 12V battery, remove the right front wheel, brake caliper, and rotor. Secure the front end with jack stands.
2. Removal:
   • Detach the steering tie rod end, upper control arm, lower control arm, and sway bar link from the knuckle.
   • Press out the old wheel hub bearing (replace with 1043285-00-A for best results).
3. Installation:
   • Press the new hub bearing into the knuckle, torqueing the retaining nut to 220 Nm.
   • Reattach components with precise torque: control arms (130 Nm), tie rod end (85 Nm), sway bar link (50 Nm).
4. Critical Alignment: Perform 4-wheel alignment to reset right front camber (-1.0° ±0.3°), caster (6.5° ±0.5°), and toe (0° ±0.1°).
